Mafuyu from kanojoxkanojoxkanojo?

Cover artist is Key. Same as the first non-colour chapter

Who's the cover artist?

i have read one hen about 2 school girls in uniform exchange with about 30yo man for the gold card or rare symbol, but i dont remember exactly, that maybe have tags like this: schoolgirl, uniform, mind control, harem, group. Hope someone can find this for me, thank you so much. Or if you know some story like this, pls name that.
